How to apply a casing waterproof sealant ?

Preserving the integrity of your home's foundations against moisture is a primary concern. Applying a tanking plaster is a crucial step in this process. However, this process may seem intimidating to those who are not familiar with its intricacies. In this blog, we will strive to demystify the surrounding mysteries and provide you with practical tips for an effective application of tanking plaster. We will delve into the crucial steps and recommended methods to ensure that your home remains optimally protected against moisture infiltration. Our goal is to equip you with essential knowledge to maintain your foundations and preserve the quality of your dwelling.

1. Understanding the importance of tanking plaster:

Before delving into the application process, it is essential to grasp the fundamental importance of tanking plaster. In essence, it serves as a waterproof barrier that prevents any water intrusion into the foundations, thereby avoiding complications related to moisture and mold formation. This protective layer is therefore crucial in preserving the integrity of your home's structure by ensuring adequate waterproofing and minimizing potential moisture-related degradation risks. A thorough understanding of its role is the starting point for an effective and lasting application.

2. Preparing the surface:

Meticulous preparation of the surface is a determining factor in ensuring the success of tanking plaster application. It is imperative to begin this process with a thorough cleaning of the target surface, rigorously removing any impurities, dirt, and existing coatings. Additionally, it is essential to address the repair of any cracks or imperfections on the targeted surface and ensure that it is perfectly dry before commencing the tanking plaster application. A well-executed preliminary step guarantees a surface conducive to adhesion and the effectiveness of the plaster, thereby contributing to the longevity and efficiency of moisture protection.

3. Choosing the right tanking plaster:

Various tanking plaster products are available on the market, and it is essential to select the ideal product based on your specific needs. These plasters come in different formulations, each tailored to particular conditions. Some are specially formulated for application on porous surfaces, while others are more effective on concrete foundations. Before starting the application process, it is imperative to consider these factors and consult the manufacturer's recommendations. To simplify your task, we highly recommend Ferber Painting's tanking plaster, a product renowned for its exceptional adhesion and moisture resistance. This smart choice will ensure reliable protection for your foundations.

4. Applying the plaster:

Once the support is properly prepared and the right plaster is chosen, the next step is to proceed with the application. Carefully use a brush or roller to ensure even application on the targeted surface. Pay close attention to adhere to the manufacturer's instructions regarding the thickness of the layer to apply and the necessary drying time. This attention to detail during application ensures optimal finish and maximum effectiveness of tanking plaster, thereby enhancing the protection of your foundations against moisture infiltration.

5. Adhering to drying steps:

When your surface is prepared, and you have selected the appropriate plaster, it is crucial to follow a precise application process to ensure optimal protection. Apply a minimum of two coats, allowing a 6-hour interval between each coat without wetting between them. The first coat, with a thickness of approximately 2 to 3 mm, should be reinforced with an open mesh. Wait for 24 hours after the first coat before applying the second, with a thickness of about 1 to 2 mm. A third coat (optional) of 1 to 2 mm is recommended for surfaces subjected to high counter pressures. Maximum performance is achieved after 28 days of drying, but light traffic may be allowed after 48 hours at 20°C and 60% relative humidity. Strictly adhere to these steps for a successful application.

By adopting this methodical approach, you will be able to establish efficient tanking plaster to secure your foundations against water infiltration risks. The importance of carefully preparing the surface, selecting the appropriate plaster, and strictly adhering to drying times cannot be overstated. By incorporating these practical tips into your process, you can acquire unmatched mastery of tanking plaster application, thus ensuring the longevity and strength of your structure. Always remember that protecting your foundations is essential for preserving the long-term quality of your home.
